30 day challenge

Ok I need your help everyone. I want to do a new way of a 30day challenge.

But every month do a new challenge based off of something, like for january I want to do a 3 day challenge of "research" on stuff to do with my kids and I's health.
Like day 1) reaserach cows milk and why its not good, and alternatives to it.....

And so on,

February do a new craft with the kids every day etc....

So for january I need topic ideas to search. Everyday, so I can base my own ideas on what I would like to change etc....

So if you could please help me with the topics it would be greatly appreciated.......Also is it a lame and nerdy idea? My bd thought so. lol
